Detachable split efficient compressor air cylinder base and assembling method thereof

Abstract

The invention discloses a detachable split efficient compressor air cylinder base. The detachable split efficient compressor air cylinder base comprises a lower base (8). The air cylinder base is provided with an upper cylinder body (6). The upper cylinder body (6) is in fastened connection to the lower base (8) through an upper cylinder body fastening screw (11). The invention further discloses an assembling method of the compressor air cylinder base. By adoption of the above technical scheme, the split detachable air cylinder base is reasonable in structure design, and clamping hidden dangercaused by uneven chamfering and edge overturning is reduced; and the situation that refrigerating machine oil enters a compressor cylinder hole through splashing and then enters a refrigeration system is reduced, heat conduction and heat exchange of two devices of the refrigeration system are improved, the refrigerating amount of the compressor is increased, and the refrigeration efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration compressors. More specifically, the present invention relates to a detachable split-type detachable split-type high-efficiency compressor cylinder block. In addition, the present invention also relates to an assembly method of the detachable split-type detachable split high-efficiency compressor cylinder block. Background technique [0002] In order to facilitate the assembly of the piston and connecting rod, the cylinder block of the existing compressor is generally provided with a crescent groove above the cylinder body of the cylinder block, and the design of the crescent groove provides a space for the assembly of the piston pin and the connecting rod. However, as far as the overall performance of the compressor is concerned, the crescent groove has no practical significance except for the assembly of the piston pin and connecting rod; at the same time, due to the existence of the cresc...

Problems solved by technology

However, as far as the overall performance of the compressor is concerned, the crescent groove has no practical significance except for the assembly of the piston pin and connecting rod; at the same time, due to the existence of the crescent groove, it is necessary to set chamfers around the crescent groove. Uneven corners or chamfering and flanging are very likely to cause the compressor piston to get stuck, resulting in the failure of the entire compressor; what's more, the existence of this crescent groove will cause the compressor refrigeration oil to be pulled to the top of the short shaft of the crankshaft by centrifugal force. During the splash lubrication process, it becomes an important channel for the refrigerating machine oil to enter the refrigeration system. When the refrigerant enters the evaporator and condenser of the refrigeration system, it will occupy a part of the volume and affect the heat transfer. Because the refrigerant is mixed with oil, the refrigerant participating in the refrigeration cycle The reduction of purity and cooling capacity per unit mass leads to a decrease in compressor cooling capacity and COP value, which is obviously inconsistent with the concept of high efficiency, energy saving and environmental protection advocated by the society.
